Check and setup your coulor setting.Good luck...

hi,

As you mentioned there is problem with the T-con (LCD pixel driver) board. This board drives the Pixes in the rows and columns of LCD pannel. there will be two connections from this board to LCD pannel. Normally in LCD tvs this board is located in the bottom center coverd by metal cover or aluminium foil to avoid interfearence. First of all do one thing rmove the connections from this board and reconnect it again. some times improper contact can cause these type of problems. Normally there is no repair possible with this board. so you have to repace the board if the problem previles. have added the picture of T-con board for your refference.


ok

Good day to you and welcome to fixya..

That problem is usually have 2 causes..Its either power supply board or main board..

Please take this steps on how to determine the problem:
1. Open the back cover.
2. Check the power supply output...It should have 5vdc for the main board..12vdc or 16vdc for the audio and 24vdc for the back-light inverter..
3. If those 3 voltage supplies have encountered voltage drop...The problem could be on power supply board..
4. If the power supply output is normal..The problem could be on the main board...
5. If the problem is power supply you should check if the capacitors are bulged on the top and try to replaced it..If you can't do that you can purchased new power supply board..
6. If the problem is on main board there is no D.I.Y repair on that so you need to buy a new main board that fits to your TV..

You have a better chances if you have failing capacitors on the power supply board..

Please watch this videos about capacitors..








Hope this solution will be helpful..

Thanks for using fixya...

Your TV will accept Component, Composite, HDMI and DVI-I inputs. Your computer will need to have a video output that matches one of those on in the list above. The DVI-I or HDMI will provide the best looking picture and is by far the most popular on modern computers. Both the DVI & HDMI jacks are for digital signals.

The standard, run-of-the-mill VGA jack on your computer can be adapted to connect by purchasing a quality cable with a DVI-I connector on one end and a VGA connector on the other. You can also purchase an adapter that will do the same thing instead for less money. If you need a long cable, purchase a quality cable instead of the cheapest one available. You will see a difference with cheapo cables. This will send video to the TV, but audio will be from the computer, unless you send the stereo signal from the computer to a seperate amplifier and speakers.

The HDMI jack will send both video and Dolby Digital audio to you TV all in one cable / connection. Of course, you need a HDMI jack on your computer and an HDMI cable to interconnect. Upgrading a desktop computer with a new video card that has HDMI jacks might be the way to go - but if you're using a notebook, this may be impossible to do.

Good luck! If my answer was helpful, please rate it "4 thumbs up." Thanks!

Are you getting any flashing codes? These codes can tell us what the issue is by the number of flashes on the power light. Most common issue in todays tv's are bad capacitors on the circuit boards usually the power supplies go first due to heat. There are no resets if the set does not power up you can try and unplugg for several hours and see if it something that might reset it self but if it does not come on then a service call is needed to find the issue. Check the outlet for power while your at it to rule this out. There are some manuals that contain diagnostic info in the manual, check yours to see if it has any info that might help.

Yes try to look for the AV format its in the menu setting.

It may have bad power supply due to bad caps, or it is in safety shutdown/restart mode due to shorted circuits, you need to do in-depth troubleshooting.

Or www.digikey.com, just make sure to use caps with low ESR, 105c, high ripple current and long life rating such as PANASONIC FM or FC series.

Use optical cables out to your surround sound. It works the best.

Hi patricia_597,
Unplug the unit from the outlet, then while unplug, press and hold the power on button for one minute to drain the voltage and refresh the boards...
Try to open again and see if the symptoms remain the same...
If yes, the power supply board produced an out-of-regulation condition and disable the unit. The most common caused of this symptom is the leaky/dried filter electrolytic capacitor in the output of the power supply section. It will drop the voltage from normal and trigger the blinking of the led light. It will not power up unless isolated the faulty parts.
Leaky capacitor sometimes has a bulged/dome at the top but not all. Dried capacitor has no physical indication of fault and looks new and in good condition but actually not. You must have a capacitor checker to determine its condition and pinpoint the faulty one.
If you don't have necessary tools and test instrument and can't troubleshoot the unit yourself, I would advice you to look for a qulified technician to isolate the symptoms..
Also check if your unit is under warranty period, avail it because the manufacturer will fix it for free. Don't attempt to open the back panel because it will void the warranty.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.
